In PH scale (0-14) messurments,at PH is 7 (nuetral) and 7
to 0 the acidic nature increses,7 to 14 the basic nature
increses.
Eg; 1.PH;3 is more acidic then PH;4
2.PH;9 is more basic then PH;8

Answer / rakesh
pH is a measure of the acidity or basicity of a solution.
It is defined as the cologarithm of the activity of
dissolved hydrogen ions (H+). Hydrogen ion activity
coefficients cannot be measured experimentally, so they are
based on theoretical calculations. The pH scale is not an
absolute scale; it is relative to a set of standard
solutions whose pH is established by international
agreement.
Pure water is said to be neutral. The pH for pure water at
25 °C (77 °F) is close to 7.0. Solutions with a pH less
than 7 are said to be acidic and solutions with a pH
greater than 7 are said to be basic or alkaline. pH
measurements are important in medicine, biology, chemistry,
food science, environmental science, oceanography and many
other applications.
